Arco vs Kalymnos

Hi there, I'm a climber from Asia, and planing a rock trip (focusing on sports climbing) this July for one month in Europe. Last year I climbed in Kalymnos for 2 weeks, and I have to say this is really a climber's paradise: super quality of rocks and routes with easy access (dozens of crags with in walking distance, and you can rent scooter at very reasonable price for further crags), comfort and cheap accommodation ( we stay at a studio at €10/person/night) and yummy food (at first we planned to cook, but found it totally unnecessary because there are many affordable seafood restaurant at a stone's throw away). This year I planned to go to a new place, and after a bit of research, I found Arco might be a good option. But I'd like to know more about Arco, and appreciate if anyone can share anything in the following aspects: Rock/Routes quality: I know it's limestone, how is it compared to Kalymnos? Access to the crags: how many crags are with in walking distance? Is car necessary? Accommodation: The budget option will be camping. I have never camped in Europe so I don't really understand the system. E.g http://www.arcoturistica.com/en/camping-arco/camping-e-servizi/pitches-price.html, in this price list, will they provide caravan? Or I need to stay in our own tent? If they do, so the price for 2 person will be the price of PLOT of GROUND + price of ADULYS x 2? Food: will there be restaurants around the camp? And what is the average price for an average meal? Thanks again, and will be happy to hear other climbing area suggestions.
